São Tomé is the capital and largest city of São Tomé and Príncipe, a small island nation in the Gulf of Guinea, home to approximately 90,000 residents. It operates on Greenwich Mean Time (GMT, UTC+0). The country sits almost exactly on the Equator and Prime Meridian intersection — the mathematical centre (0°, 0°) of the Earth's coordinate system falls in the Gulf of Guinea just south of the islands. São Tomé and Príncipe was uninhabited when Portuguese explorers arrived in the 1470s and became one of the world's first and most important plantation slave economies — sugar production here pioneered the plantation system later replicated in the Americas. Today the country is one of the world's smallest nations by area and population. It has significant offshore oil potential and is diversifying into cacao production (producing premium chocolate) and ecotourism. The Portuguese colonial architecture, Creole (Forro) culture, and unique biodiversity of these forested volcanic islands make São Tomé an intriguing destination.
